报告内容:Humanitarian logistics often faces the challenge of dealing with uncertainties when developing a rescue strategy in response to the occurrence of a disaster. We develop a distributionally robust model (DRM) for the multi-period location-allocation problem with multiple resources and capacity levels under uncertain emergency demand and resource fulfilment time with only limited distributional information being available in humanitarian logistics. We show that the model can be equivalently reformulated as a mixed-integer linear program, and develop a tailored branch-and-Benders-cut algorithm to solve it. To enhance the efficiency of the algorithm, we propose some improvement strategies, including in-out Benders cut generation, dual lifting, and normalization of the dual variables. We perform extensive numerical studies to verify the performance of the developed algorithm, assess the value of the DRM over the corresponding deterministic and stochastic models, and discuss the impacts of key model parameters to gain managerial insights, particularly for the decision-maker planning on allocating resources based on tradeoff among the operating cost, equity and efficiency. We also demonstrate how our model performs had it been used in the actual earthquake that occurred in Jiuzhaigou, China. 报告人简介: 殷允强,电子科技大学经济与管理学院教授、博士生导师,国家万人计划青年拔尖人才,四川省杰青,四川省海内外引进高层次人才。主要从事智能决策与优化,生产与物流运作管理,数据挖掘等方面的研究。以第一或通讯作者在NRL、EJOR、TRE、Omega、IEEE Transactions on Cybernetics、IEEE Transactions on SMC等国际主流期刊发表SCI论文60余篇。主持国家自然科学基金项目4项,国家社科重大项目1项(子课题负责人),四川省杰出青年科技人才项目、国家留学基金委中法蔡元培国际合作项目等省部级项目多项。2014-2021连续8年入选Elsevier 中国高被引学者榜单。现任Complex & Intelligent Systems、International Journal of Production Research等多本SCI期刊的副主编、首席客邀编辑,中国管理科学与工程学会理事,中国优选法统筹法与经济数学研究会船海经济管理专业委员会副理事长,中国优选法统筹法与经济数学研究会智能决策与博弈分会秘书长兼常务理事以及中国运筹学会排序专业委员会等多个分会的理事。 |
